BOX-SANDING MACHINE Specification of Letters Patent.

Patented Oct. 20, 1908.

To all whom it may concern:

Be it known that we, THOMAS A. PALMER, of Akron, Summit county, Ohio, and CARL A. CARLSON, of Barberton, in the county of Summit and in the State of Ohio, have invented certain new and useful Improvements in Box-Sanding Machines, and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which- Figure 1 is a perspective view of a box sanding machine embodying our im rovements; Fig. 2 a top plan view thereo Fig. 3 an end elevation; Fig. t, a vertical section on the line -m of Fig. 2, arts being shown in elevation;l Fig. 5 a detail section through the sand-throwing mechanism; and Fig. 6 a detail perspective view of the sand wheel.

Letters of like name and kind refer to like parts in the several figures.

The object of our invention is to produce a thoroughly practical and simple machine for applying sand to the surfaces of match boxes to provide Scratch surfaces thereon, and to this end, said invention consists in the sanding machine constructed substantially as hereinafter specified.

Our machine has been desi ned to apply sand to an exterior surface o boxes of the class consisting of a tray or receptacle part, and a cover part in the form of a flat-sided tube, the cover part being commonly called the shuck or slide, and the sand being applied to it.

Generally described, our machine com prises a rotary head from the side or periphery of which projects a series of radial, equi-distant fingers, adapted each to receive and support a box shuck, and by the rotation of the table, present the same successively to a glue applying device, a sand applying device, and finally to a discharge device.

The head A, is preferably ring-form in shape, and is mounted upon a table B on the top of a standard C, being journaled by a' vertical ring D bolted to the table B by a horizontal flange Z and having a second flange l1 that overlaps thev head A. The shuck-receivin fingers E and E, are each in the form o a bar that has a shape and size in cross-section agreeing substantially with the like features of the shuck; and as Shown, each bar is seated at its inner end in a radial recess in the head A, and is fastened by screws to the latter. Lugs a and a project from the head, on each side of the bar, and the outer ends of the lugs form Stops to limit the end-wise movement of a shuck in being slid on to the bar. The outer end of the bar is rounded or beveled to enable a shuck to be readily shoved upon it.

A shuck, after being placed on the finger, or bar, is by the rotation of the head, carried to a glue-applying device, which comprises a bar F and a pan Gr containing glue, into and out of which the bar F is moved, taking glue upon its upper side and app/lying it to the side of the shuck over the underside of the holder bar, the glue bar F being attached near one end to a vertical rod I-I connected with a horizontal arm I fastened to the upper end of a vertical bar K. The bar K is reciprocated vertically by a cam, eccentric, or other means on a main or driving shaft L supported in bearings on the standard A, and it is guided in its movements by being passed through a post or upright M on said standard. To provide for the contingency of a shuck not being on a finger or bar E when thelatter is presented over the glue bar F there is a cavity or recess c in the bottom of the bar E of a size slightly larger than the glue-carrying part of the bar F. There is thus no surface on the bar E to which glue can be applied by the raising of the glue bar in the absence of a shuck. It is desirable that the glue bar shall bear against a shuck with a yielding pressure, and for this purpose, the rod H is not rigidly connected to the arm I but yieldingly, it being passed through an opening in said arm, and having a collar L below the arm, and a head h1 above it, between which and the arm is interposed a spring h2.

After having received the glue, the shuck by the farther rotation of the head is carried to the sand-applying mechanism, which, generally, is of usual construction, comprising a dish-form box or receptacle N supported beneath the path of the shuck-holding bars E and E, upon a bracket O attached to the standard A, and a sand wheel P upon a shaft Q by which the wheel is rapidly re# volved to cause it to throw sandagainst the glued surface of the shuck. The sand wheel is of usual construction in that it has a series of wings or vanes runnino` parallel with its axis, but the wheel sur aces between the lendnearest the head A.

wings incline in radial directions from end 13o-end, being vnearest the wheel aX-is` atl the This inclination of the surface of the wheel, effects the drawing or feeding' of the sand to the wlieeh-aird insures that at all times there shall be an amp-le fquantity of sand for-the wheelfto catch up and throw to the shuck. Sand is delivered to the box from an ordinary hopper Rand the wheel draws the sand from.

the side of the box to which'it is delivered Efrom the' hopper. The wheel shaft Q passes through an opening' in the side wall of the 'box N'and to prevent sand working along the shaft through such opening, a pocket S is kprovided for a packing T around the shaft,

'of some suitable material, such as waste and a lubricant, preferably graphite. "Suitable 'bearings for the shaft' are provided on the bracket O, and for rapidly revolving the shaft, a pulley Uthereon is belted to 'a wlieel'V on a shaft beneath, supported at an' angle to and geared bybevel gears, to the 'main V'shaftV L.

Farther rotation Aof the head A brings the shuck to the ejecting or vdischarging mechlanism,'which as shown, consists vof a vertical finger or plate IV havingv a'beveled lower ed'ge'in the plane lof the upper sides of' the Shiloh-holding bars'F and F, and adapted tofv engage the shuck on its innerend,'and by an;`

"outward movement, sli'detthe` shuck o' they bar F. Saidplate W' is fixed to the outer; v'end of a bar X placed'if-n a guideway that@ extends radially on theringflange d1, :and reciprocated in such guideway by an eccentric Y,withfwhich it is lconnected by a rod;

yfsaid eccentricbeing on ashaft Z jour-1 naled in bearings Yon the 'ring flange (Z1, and;

revolved" byA sprocket gearing from the mai-n shaft L.

F orl automatically revolving the head A` step by'step, we employ a pawl` and ratchet lmechanism, that consists of' ratchet teeth al 'and a1- on the underside of the head, and a pawlvAl-hnng on the upper end Aof va lever Bl'that is pivoted at its lower end to the standardf C, and isvibratedy by a crank or eccentric connection'with thel driving shaft, L. To prevent -overthro-wgof the head A by thepawl and ratchet mechanism, 'and thus insure the proper Vrelative positions of a shriek-holding bar and the glue bar, and the shuck ejectorlnger, means lareprovided to positively arrest the motion of the head 'A at the eXactlimit designed. As' shown, such means comprise aseries of'ratchet` teeth a2 and a2 on the head A, and a ld-og C1 pivoted Ito the standard C, and weighted to hang normally out of engagement `with said' teeth. A stud or projection 7)' on the --side of the lever B1, strikes the underside of the Adog C, Vwhen said llevery completes its yhead-moving motion, and 'puts the dog in engagement with one 'of the'stop teeth. Gravity, or vother Ymeans may be provided to disengage the dog from its tooth, but preferably this is'ldone by attaching to the lever'B1 a finger b1 that passes beneath the tail of the dog, 'on the forward-motion of the lever B1, and has a raised surface b2, in whose path on the return ymovement of the lever, saidtail extends, and which, therefore, then eno'ages the tail, and raising it, frees the dog from the stop tooth. v

rihe operation of our -machine is, briefly,

as follows A boy, or other operator, .places the shucks to be sanded upon' the lingers or barsF andlF, taking a shuc'k in each hand,

Aand then nally'to the Aejector,`which is at 'the inner limit of its motion when a shuck is presented to it, and is moved ontwardto eject the shuck while the head is'at rest.

It is' to be understood that though we have specifically described 'certain details of construction as characterizing our machine,we do .not thereby intend to restrict the scope of the invention, broadly considered, 'to suoli, or

' any specific details.

Having thus described our invention, what 4`we claim is l. 'In aboli-sanding machine, the combination of sanding mechanism, a rotary head with a horizontal series of :lingers rupon which boX sh'ucks are thrust,and an 'ejector for removing shucks' from said ngersr com- :prising a reciprocating bar having a shuck engaginginger, substantially as described.
